Re: Glade & ComboBoxEntry

[Chris Scaife <scaife chris gmail com>]

Thanks Christoph, that was a good help and exactly what I want to do, but I'm still struggling with the glade side of things. You see I want to define columns and rows in the glade file but I just can't make that work. So in the hope someone can see what I'm doing wrong I attach a .tar containing my simplified .glade and .cc file.

Basically it's this bit I want out of the code into the XML:

// Tree model columns: but I don't want this in the code

// I think glade can put it in the XML

struct ModelColumns : Gtk::TreeModel::ColumnRecord {

ModelColumns() {

add(m_col_name);

}

Gtk::TreeModelColumn<Glib::ustring> m_col_name;

} m_Columns;

and this bit

m_refTreeModel = Gtk::ListStore::create(m_Columns);

pComboBoxEntry1->set_model(m_refTreeModel);

// It be nice to put initial rows in the glade file too

// although I do want to add the ones that the user creates

Gtk::TreeModel::Row row = *(m_refTreeModel->append());

row[m_Columns.m_col_name] = "Option 1";

row = *(m_refTreeModel->append());

row[m_Columns.m_col_name] = "Option 2";

row = *(m_refTreeModel->append());

row[m_Columns.m_col_name] = "Option 3";

   pComboBoxEntry1->set_text_column(m_Columns.m_col_name);

Thanks for all and any insights :)

Hi,

create a combox, and a liststore in glade (assign the liststore to the
combobox entry.

Then in c++, if you use Gtk::Builder (instead of libglade):

Glib::RefPtr<Gtk::Builder> b =
Gtk::Builder::create_from_file("simple.glade")

m_liststore = dynamic_cast<Gtk::Liststore>
b->get_object("liststore_name");

Gtk::ComboBoxEntry *combo;
b->get_widget("combox_name", combo);

combo->signal_changed().connect(sigc::mem_fun(this,
&App::combo_changed));

void App::combo_changed() {
Gtk::TreeModel::Row row = *(m_liststore->append());
row.set_value(0, combo->get_active_text());
}

well i think almost like this ;)

best regards
